My experience has been that if a pullet hits point of lay at the same time that daylight hours are decreasing, she might wait until the following spring to begin laying. In those instances, the timing of first egg has more to do with increasing daylight hours rather than hold old the pullet is.
A similar phenomenom occurs in horses, and broodmares are routinely placed under lights in December, to trick them into cycling in early February so foals are born as close to January 1 as possible. Otherwise, the mares would be in "anestrus" and not cycle or have erratic cycles.
You can place your pullets under lights, but I don't know if it's worth the cost of electricity for a few weeks earlier egg production.
This is exactly what happened to me and my Lavs. Hatched them last April 2011 and I did not begin getting eggs from them until this past month... 10 months later...
